Title

Flatworms of Coexistence

Problem Scenario

Why are they're so many organisms?

Broad Question

Can flatworms coexist?

Specific Question

Can species of Flatworms coexist with a limiting resource?

Hypothesis

I think that both species of flatworms will coexist on a limiting resource.

Graph of Hypothesis

Variables

Independent Variable:

Habitat types, types of planaria.

Dependent Variable:

Number of planaria left.

Variables That Need To Be Controlled:

Numbers of planaria, water source, temperature of water, containers.

General Plan

My plan is get two species of Flatworms and put it in an environment then put a limiting resource and see if they coexist. I have two different types of habitats.There is two cups of each habitat. I put a little bit of hard boil egg in the four containers and then see the results.

Potential Problems And Solutions

They will die in the first day and I will get worms. no data. I would do something else with my spare flat

Safety Or Environmental Concerns

Take good care of them.

Background Research

Flatworms are unsegmented worms that are flattened completely. That means their bodies are so flat that they can hide underneath river stones and under surfaces like that. Not only do Flatworms or Planaria live in rivers they also live in the ocean, but my flatworms lived in freshwater so they live in the river. The surface of their bodies have tiny little hairs that are always moving. That allows them to glide over rocks and plants and hard surfaces like that. Flatworms have no skeleton in their body. Which makes them flexible.

Detailed Procedure

The way I did this project for coexistence of flatworms was I had four cups two with the same environment. There are two different environment so each to cups have the same environment. Two cups have plants and the other has nothing. I have four flatworms in each cup they're type of different flatworms and then I see if they coexist. That is how I did my Flatworm experiment.

Data Analysis

I had four cups. Each two cups have different habitats or environments. For cup 1 it has no environment. It started out with 2 different species Dotted and Non-Dotted Flatworms so they were four different types and by day 2 of the experiment all Flatworms were dead. This proves that this cup of Flatworms did not coexist with a limiting resource. For cup two we had the same amount of worms and the same environment the non-dotted species of flatworms lasted longer than the dotted flatworms. The Dotted Flatworms lasted about three days and Non-Dotted lasted four days. Again proving that they did not coexist. For Cup 1 E has the same amount of flatworms as every other cup but it has different environment Dotted lasted longer than Non-dotted Dotted lasted about seven days and Non-Dotted lasted four. Proving they did not coexist. For the last cup it has the same environment as Cup 1 E and Non-Dotted lasted longer than Dotted Flatworms. The Dotted species of Flatworms lasted four days and Non-Dotted lasted six days. Proving again that they can not coexist.

Conclusion

My hypothesis was, I think that both species of Flatworms will coexist on a limiting resource. My data says the exact opposite. It proves that my hypothesis was totally off.

Discussion

There was a few patterns in this project. One is that the flatworms didn't really compete for the food they share it. But the way it ended is they all died in four days and they did not coexist. That happened to the rest of the cups of Flatworms. Another they didn't use any strategy like for example in Cup 1E they didn't use any of the plants to help them get the limiting resource same thing with Cup 2E didn't use any of the plants.

Benefit to Community and/or Science

This benefits to the science community because there is a huge debate about how much it takes to coexist and this project is good evidence how much you need to coexist.

Abstract

I chose this type of project because earlier in the year we did this thing pretended to be birds and have a limiting resource see the outcome and do this whole project on it. I ended up loving this project and I did really well in the project grade wise. The way I did this project was I had four cups with two different enviroments one envirorment in each two cups. I put alittle bit of hard boil egg and put it in each cup. My hypothesis was I thouhgt they were going to coexist and it ended up n=being the exact oppisete.
